To all whom it may concern.' a typewriter frame in which a carriage isBe it known that I, ALVAH C. RoEBUoK, a transversely movable, thecarriage being citizen of the United States, residing at hererepresented only in part and that part Woodstock, in the county of`McHenry and designated by the reference numeral 6. Se-

This invention relates to a typewriter In its preferred form, the marginstop 1o margin stop and more particularly to a recomprises a housing orbody 9 which is a leasable margin stop located to control the freelymovable along the bar 7, and pivoted left-hand margin, and isconstructed so that on the body 9 is a leverl0 having a forked it may bequickly released when it is deend 11 for engaging the teeth 8 at thesides sired to write marginal notes on the` leftof the bar 7, and with aknob 12 at the other hand side of the sheet, without losingv the end ofthe lever by means of which the 7o adjustment of the margin stop as setfor the forked end 11 may be released from enregular margin. Theprincipal object of gagement with the teeth. A spring 13 is theinvention is to provide a new andimdisposed between the body 9 and theknob proved construction for accomplishing this end of the lever whichtends to hold the result. forked end of the lever in engagement with 75For the attainment of these ends and the the teeth of the bar 7.Extending from accomplishment of other new and useful obboth sides ofthe body 9 are pivots 14C on jects as will appear, the inventionconsists which is mounted a release lever 15 having in the features ofnovelty in the construcan arm 16 which extends above the body of tion,combination and arrangement of the the stop for manual operation. Theother 89 several parts generally shown in the accomarm of the lever 15comprises an engaging anying drawing and described in the speciportion17 and an angular abutment 18. cation, but more particularly pointed outTo accommodate this angular abutment, the in the appended claims. lowerportion of the body 9 is formed with 39 In the drawings, Figure 1 is aview of ceran angular notch 19 in which the abutment 85 tain parts of atypewriting machine, some 18s adapted to engage.

new, the novelty in this margin stop lies in the engaging arm 17 of thelever may be its simplicity and its very rigid form of conmoved in thedirection of the body 9, therestruction which is important because ofthe by unseating the abutment 18 from its impact against this part eachtime the carnotch 19.-

riage is returned to the beginning of the Secured to the frame 5 of thetypewriting 100 line. It is difiicult to make economically a machine inthe path ofthe engaging portion stop of this kind suficiently rigid towith- 17 of the lever 15, is a bracket 21 provided stand successiveimpacts and at thesame with an upturned end and sides 22 which timerender it possible to quickly release forms a pocket for receiving theengaging 5@ the stop at any desired time without losing end 17 of thelever. The top of this bracket 105 the adjustment of the margin stopitself, is spaced from'the lower part of the body especially when themargin stop 4body is portion 9 of the margin stop so that when movable.the releasing lever is moved upwardly to Referring now more particularlyto the the dotted position shown in Fig. 2, the mardrawing, the numeral5 designates generally gin stop can be moved past the stop bracket Ll@21, and consequently the carriage to which the bar 7 is attached may bemoved in this direction, permitting an operator to write on theleft-hand side of the margin determined by the margin stop, withoutlosing the permanent adjustment of the margin stop. With thisconstruction, it will be seen that the impact of the engaging arm withthe stop bracket is not communicated directly to the pivots 14: of thereleasing lever, but is communicated to the body 9 of the stop which isheld firmly in position by means of the forked end of the lever 10,since the abut-' ment 18 is normally in engagement with its angularnotch 19. Thus the pivots 111 are relieved of the strain due to thesuccessive impacts of the margin stop with the stop bracket. The stopbracket itself is strengthened by reason of the'upturned sides whichform a pocket for receiving the engaging end of the lever 15.
